Airborne precautions target infections that spread through tiny particles that can float in the air for long periods and be inhaled by others. Because these organisms can travel beyond immediate contact and stay suspended, preventing transmission requires environmental controls and protective gear that specifically address inhalation risks—such as placing the patient in a negative-pressure isolation room, keeping doors closed, and using properly fitted respirators (N95 or higher) for staff. Infections like tuberculosis, measles, and varicella are classic examples managed this way because they spread through the air rather than by direct contact.

Direct skin contact is addressed with contact precautions, which focus on touching contaminated surfaces or skin. Fecal-oral spread occurs through ingestion of contaminated material and is prevented with diligent hand hygiene and surface cleaning, not airborne measures. Bloodborne transmission involves contact with infected blood and is managed with standard precautions and barrier protections, not airborne precautions.
